CRUST: In a small bowl, combine cracker crumbs and sugar; add butter and stir until moistened. Press mixture into prepared baking pan. Bake for 7 to 10 minutes or until set. Move to a wire rack to cool completely.

FILLING: In a large bowl, beat cream cheese, sour cream, sugar, flour and vanilla until smooth. Add egg, and beat on low until just combined.

Pour ¾ cup batter into a small bowl. Add pumpkin, brown sugar and cinnamon, stirring until well blended.

Pour plain batter over cooled crust. Drop dollops of pumpkin batter over the plain batter. Cut through batter with knife to swirl.

Bake at 325 degrees for 20 to 25 minutes or until center is almost set. Cool on wire rack for 1 hour. Cover and refrigerate at least 2 hours to overnight.
